  2. Back up the engine files that will be replaced in Anomaly\\bin\\.
  3. Download AnomalyDX11AVX.exe and AnomalyDX11AVX.pdb, then place them into Anomaly\\bin\\ and confirm file replacement when prompted.
  4. Launch the game through MO2 (Mod Organizer). Installation and launch examples are shown below.
  5. Compatibility with existing save files is not guaranteed. Starting a new game is recommended.
  6. If you encounter errors or crashes, send us the logs from AppData\\Roaming\\QUARK ENGINE\\ERROR\\ via Discord. These files help identify the cause of the issue and further improve the engine.
